Brian Robison injury: Vikings DE hurts shoulder, questionable to return

The Minnesota Vikings may be without defensive end Brian Robison for the remainder of Sunday's game against the St. Louis Rams after he suffered a possible shoulder injury in the first quarter. He's officially being listed as questionable to return this week.

After temporarily staying down on the play that he apparently injured himself on, Robison was able to walk off the field under his own power. That doesn't necessarily say as much about the state of his shoulder, though, which is reportedly the location of the injury.

Robison, who emerged as a starter with the Vikings last season, continues to be a solid part of Minnesota's defense this year. Including his early sack against St. Louis before leaving the game, Robison has recorded 36 tackles, 7.5 sacks, seven defended passes and two forced fumbles in 2012.

With the sixth-year pro out of the game, it appears that Everson Griffen will get most of the snaps in his place.
